Parameters
entry (required): Entry point file--compile: Create standalone executable--minify: Minify output
Execution
Production bundle:
bun build $ENTRY --outdir=dist --minify --sourcemap=external
Standalone executable:
bun build --compile --minify $ENTRY --outfile={{ OUTFILE | default: "app" }}
Development bundle:
bun build $ENTRY --outdir=dist --sourcemap=inline
Build Targets
bun build $ENTRY --target=browser --outdir=dist
bun build $ENTRY --target=bun --outdir=dist
bun build $ENTRY --target=node --outdir=dist
Post-build
- Report output file sizes
- List generated files in output directory
